Throttling limits on CPU i78750H power usage
Hey everyone. I just got a new laptop with an i78750H. During a stress test, it reaches up to 70°C (max 72°C) and after about 20 seconds it shows "Power Limit Throttling." The CPU should hit 4.1Ghz but only goes to 3.9Ghz and then starts dropping due to throttling. Any solutions or fixes?
It seems you're questioning whether your setup pushes physical limits. It might be feasible to disassemble the laptop and install a more effective cooling system, though modern designs often prioritize compactness. Could an external fan-based solution work? Also, what model are you using?
HP OMEN 17-an107np 17.3" graphics card with 16GB RAM, Intel i7-8750H processor, 1080p display at 120Hz refresh rate.
It functions as expected. A peak of 3.9 GHz should occur when all cores are running. With up to two cores active, performance reaches 4.1. At four or more cores, you might reach 4.0. On high-end builds this could be the final limit. In laptops, they often reduce power after a while (lowering TDP) and clocks can decrease. I think this is the goal—maintaining TDP for efficiency while allowing short bursts for demanding tasks. There might be options to adjust settings, but it's unlikely to be useful since cooling won't handle higher limits. You can look in the BIOS for any adjustments; overclocking usually doesn't work outside that. Using IntelXTU drivers may help change parameters, though they're likely ignored by the BIOS. Under-volting could offer some gains but risks stability.
The Core i7-8750H features a 45 Watt TDP rating. https://ark.intel.com/content/www/us/en/...0-ghz.html This processor is built to reduce performance over time, staying under the 45 Watt limit. Some laptops offer superior cooling and let users boost turbo power significantly, enabling the 8750H to operate at its full Intel speed continuously. For example, it can maintain a steady 3.9 GHz when all six cores are engaged. This discussion on Notebook Review provides useful advice on achieving such performance. http://forum.notebookreview.com/threads/...0z.815943/ Laptops like this cater to tech enthusiasts aiming for peak efficiency from their purchase. They are straightforward to modify and can be fine-tuned for optimal speed. Many high-end models come with restrictions, preventing sustained full performance. If you recently purchased an OMEN, consider returning it to the store and informing them of your concerns about its suitability.
